At least three independent records from different recorders/locations/dates.
Breeds and has its complete lifecycle throughout the year on Corfu. Population is self-sustaining.
Regular immigrant and/or emigrant from Corfu. May also breed but is usually not present all the year around.
Found outside its normal range, such as outside its known habitat. Not enough records to confirm as a Resident or a Migrant.
A species that is expanding its range, but is not self-sustaining, and is reliant on migrants to sustain its population. This is the stage before a species becomes a resident, or a species which is right on the edge of its known distribution.
Records that have not been substantiated and therefore the existence of such a species on Corfu is uncertain.
EU Red Data Status Definitions
Not Evaluated (NE)
A taxon is Not Evaluated when it has not yet been evaluated against the criteria
Data Deficient (DD)
A taxon is Data Deficient when there is inadequate information to make a direct, or indirect, assessment of its risk of extinction based on its distribution and/or population status. Data Deficient is therefore not a category of threat. Listing of taxa in this category indicates that more information is required and acknowledges the possibility that future research will show that threatened classification is appropriate.
Least Concern (LC)
A taxon is Least Concern when it has been evaluated against the criteria and does not qualify for Critically Endangered, Endangered, Vulnerable or Near Threatened. Widespread and abundant taxa are included in this category.
Near Threatened (NT)
A taxon is Near Threatened when it has been evaluated against the criteria but does not qualify for Critically Endangered, Endangered or Vulnerable now, but is close to qualifying for or is likely to qualify for a threatened category in the near future.
A taxon is Vulnerable when the best available evidence indicates that it meets any of the criteria A to E for Vulnerable (see Section V), and it is therefore considered to be facing a high risk of extinction in the wild.
A taxon is Endangered when the best available evidence indicates that it meets any of the criteria A to E for Endangered (see Section V), and it is therefore considered to be facing a very high risk of extinction in the wild.
Critically Endangered (CR)
A taxon is Critically Endangered when the best available evidence indicates that it meets any of the criteria A to E for Critically Endangered (see Section V), and it is therefore considered to be facing an extremely high risk of extinction in the wild.
Extinct in the Wild (EW)
A taxon is Extinct in the Wild when it is known only to survive in cultivation, in captivity or as a naturalized population (or populations) well outside the past range. A taxon is presumed Extinct in the Wild when exhaustive surveys in known and/or expected habitat, at appropriate times (diurnal, seasonal, annual), throughout its historic range have failed to record an individual. Surveys should be over a time frame appropriate to the taxon’s life cycle and life form.
A taxon is Extinct when there is no reasonable doubt that the last individual has died. A taxon is presumed Extinct when exhaustive surveys in known and/or expected habitat, at appropriate times (diurnal, seasonal, annual), throughout its historic range have failed to record an individual. Surveys should be over a time frame appropriate to the taxon’s life cycle and life form.
A medium sized brown butterfly, flying in grass meadows. The forewing has a medium sized black spot, white-pupiled, upperside and underside. Males have a dark brown upperside, and the slightly larger female has a large orangish patch on the forewing. The underside is similar, the forewing is chestnut coloured with a brown border, whilst the hindwing is brown, with a paler submarginal band. Whilst the markings are variable, it shouldn’t be confused with any other species in Corfu.

Not nearly as dominant in the Corfu butterfly species community as it is in the assemblages of other more industrialised nations. This probably indicates that the butterfly fauna is a lot healthier in Corfu than is the case in many other parts of Europe.
